Airflow humidity separation mechanism of waste heat recovery device

The utility model discloses an airflow humidity separation mechanism of a waste heat recovery device. The airflow humidity separation mechanism comprises a main pipeline, a drying barrel, a motor, a filter, a main box body, a dust collector, a humidity sensor, a heater and a pipeline silencer. The dust collector is arranged at the upper end of the main pipeline, air flow enters the dust collector from the main pipeline through the pipeline, the air flow enters the volute air inlet mechanism to be treated and then flows into the centrifugal hopper to be subjected to centrifugal treatment, and dust falls into the powder barrel under the action of gravity; the heater is arranged at the right end of the main box body, airflow flows into the heater through the main pipeline, the heating pipe is heated easily, heat is kept in the heater, and secondary heating is conducted on the airflow; the pipeline silencer is arranged at the left rear end of the main pipeline, air flow enters the pipeline silencer from the main
